SLIDING-WINDOW STRUCTURE Application filed September 24, 1927. Serial No. 221,752.

This invention relates to window construction for dwellings and other buildings and structures.

An object is to provide an improved window structure including a built-in, wooden or other frame and an edgewise slidable window sash, and in this connection an object is to provide a wall frame which can be readily cut, prepared and installed by the average carpenter. An object is to provide a frame structure and its slidable sash which are devoid of any special hardware, which are of very low cost of material and of labor of installation. An object is to provide a sliding sash and its mounting frame of foolproof form and having no intricate features, and to provide a structure of substantially permanent type.

Additional objects, advantages and features of construction, combination, and details of elements and mode of manufacture will be made manifest in the following specification of the herewith illustrative embodiment; it being understood that modifications, variations and adaptations may be resorted to within the spirit, scope and principle of the invention as it is more directly claimed hereinafter.

Figure 1 is a horizontal section of the frame and top plan of the closed sash. Figure 2 is a vertical sectionof the frame and edge view of the sash. Figure 3 is an elevation of a fragment of an upper corner of the sash and its preventer roller. Figure 4 is an elevation of the lower corner of the sash; partly in section, and Figure 5 is a plan of the bottom edge thereof. Figure 6 is a top plan of the window sill. Figure 7 is a top plan of the header. Figure 8 is a detail of the sill and stile joint.

I am aware that it has been proposed to mountwindow sashes so that they may be shifted edgewise into a wall recess and my present invention is to provide a Window, of this type, of simple and practicable construction and reliable in action.

A sash W has countersunk in its lower rail element a set of ordinary, sash cord, flanged rollers 2 which project down into a longitu dinal groove 3 along the rail element. The top of the sash is provided with a set of plain rollers 4 whose function is to prevent the top of the sash from jamming against the frame header H.

The trackin rollers 2 are designed to run on a hardwood or metal parting rail 5 which is provided along a main, frame sill S and pro ects up into the sash groove 3. It will be seen, therefore, that the sash is Waterproofed by the parting rail 5 and has upper and lower rollers insuring its easy and reliable sliding action edgewise.

The frame includes a full or blind, vertical stile 8 at one side and twin stud parts 9 and 10 forming the opposite stile. The parts 8 and 10 have inside, removable stop beads 13, which, when removed, allow the sash W to he installed or dismounted. The stud or stile members 9 and 10 are laterally spaced to form a guideway for the sash and also to receive a tail part S, of the sill, which extends into the chamber in thewall formed by the outside finish 0 and the inside finish 1'. The sill tail S is supported between interior, spaced twin studs 15-16 and an end rest 17 on a partition stud18.

The sill S has its outer lip end cut back at r s to solidly inortice into the side notch 9 of the stile part 9. The arting rail 5 runs full length of the sill S- and therefore guides the sash into and out ofthe wall recess. .The stile parts 8-10 are so spaced horizontally that the sash can be put in or removed when the stops 13 are off.

When the sash is pushed back its front edge is accessible at the mouth stile 9--10. It is understood that double or twin sashes may be installed in wall, window openingswhen so desired. l

The top or header member H extends into the wall recess and has an outer, fixed stop 20 and an inner, removable head 21.

Along the inside edge of the main sill S is a finish strip or stool 22 contiguous to the sash bottom.

It is obvious that the wall body or finish ma be of various construction, the flush, bul -nose type here shown being only illus trative. 7

To prevent jamming of the pushed-back sash by the possible inward warping of the stud pieces, these may have reinforcing metal straps 25 on their edges.

The sill S has its top pitched down from about the front, lower corner of the sash.

lVhat is claimed is:

In combinatioma wall frame having opposed window studs, a sliding sash window structure, pre-cut header and sill elements each having a wide main body part exposed in a window opening and each having a. rea duced tail part extending into the wall strut.

ture and forming astreight continuous edge of the main body, the sill extending forwardly beyond the frame studs t0 the Wall face, the sill element having anupstanding parting rail from end to end forming a track and the header having a traclfless, smooth face, and a sash having a grooved bottom to receive the rail and having top rollers to run against the header face to prevent the sash from binding and having rollers to run on the rail, one ef the studs being provided With a butt shoulder and the sillbeing notched t0 giortise with and bear up against said shoul- ROY L.
